Kernel exploitation refers to cyberattacks that target vulnerabilities in the kernel - the core component of an operating system. By exploiting these flaws, attackers can gain privileged access, bypass security mechanisms, and execute arbitrary code with high-level permissions. This allows them to take full control of affected systems, install malware, steal sensitive data, or disrupt operations. Kernel exploits are particularly dangerous because they undermine the fundamental security boundaries of computers and devices. Defending against such attacks requires timely patching, secure coding practices, and robust system monitoring to detect and mitigate threats before they can be leveraged by attackers.
